Comment:
Reported on the mailing list by Philippe Carriere:
Well, from my own tests: jack starts at 96kHz with the new firewire
stack but playback streaming almost does not work (I mean, some 1/2s with
sound - apparently correct - for 10s of silence, mostly random). A point
is that everything work at 88.2kHZ (and 44.1 and 48kHz, of course); I did
not see an evident mistake in the configuration, at first glance.
Further work is clearly required.
It's strange that other rates - even 88.2 kHz - are seemingly ok. At
first glance that would suggest some sort of throughput issue. However,
the difference between 88.2 and 96 isn't all that much so it's a bit hard
to see how a modern machine would work fine with the former but fail with
the latter.
To resolve this we clearly need someone who owns a Saffire PRO 40 to pick
this up and determine what the problem is. I'll set the milestone to 2.x
for now since the timing for this to occur is completely unknown. If it
happens in the next month and makes 2.1, well and good. If not, I don't
consider it a show-stopper for 2.1.
In the meantime it would be good to hear from other PRO-40 owners to see
if these problems affect them too.
